From ad564cb0197865bb6caecd6a0ea628249c08afb2 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Tue, 31 Jan 2023 09:30:18 +0100 Subject: toolchain/gcc: clean up CFLAGS Instead of having two different ways to pass flags to the gcc build process, add them as configure args, which is a reliable way to let gcc pass them around to its various pieces. Also add CXXFLAGS, since gcc started to use c++ for itself recently (~10 years ago now).
